My daughter was playing with her 5th gen iPod Nano and somehow locked it. Now whenever the screen comes on there is a picture of a padlock. I have read that you can connect it to the "original" computer that the iPod was set up on, but it was so long ago I'm not even sure that computer is around any more. In any case, it says this is only necessary if you have forgotten the unlock code.

Here is my question: How do you enter the unlock code??? It doesn't prompt for any kind of code!
